Hi,

ER_INITIAL_PSP section was used as the Trustzone NS Agent partition stack in IPC model.

Since Trustzone NS Agent partition has changed to use private variables as its stack, ER_INITIAL_PSP related definitions and references can be removed.

Change: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/13186

This change involves all the platforms for IPC model, it removes:

• Definition of ER_INITIAL_PSP section in the linker script
• Reference of ER_INITIAL_PSP for isolation configuration in platform HALs

This can simplify the linker script a bit.

This patch is going to be put there for a while as there are holidays, but please do review it when you see this mail. Plan to merge it before end of Jan, as soon as all concerns get addressed (if there are).

Regards,

Mingyang
